Therapeutic indications:

Danazol capsules USP are indicated for the treatment of endometriosis amenable to hormonal management. Most cases of symptomatic fibrocystic breast disease may be treated by simple measures (e.g., padded brassieres and analgesics). In infrequent patients, symptoms of pain and tenderness may be severe enough to warrant treatment by suppression of ovarian function. Danazol capsules USP are usually effective in decreasing nodularity, pain, and tenderness. It should be stressed to the patient that this treatment is not innocuous in that it involves considerable alterations of hormone levels and that recurrence of symptoms is very common after cessation of therapy. Danazol capsules USP are indicated for the prevention of attacks of angioedema of all types (cutaneous, abdominal, laryngeal) in males and females. Danazol should not be administered to patients with: - Undiagnosed abnormal genital bleeding. - Markedly impaired hepatic, renal, or cardiac function. - Pregnancy. (See WARNINGS .) - Breastfe

CLINICAL PHARMACOLOGY
Danazol suppresses the pituitary-ovarian axis. This suppression is
probably a
combination of depressed hypothalamic-pituitary response to lowered
estrogen
production, the alteration of sex steroid metabolism, and interaction
of danazol with sex
hormone receptors. The only other demonstrable hormonal effect is weak
androgenic
activity. Danazol depresses the output of both follicle-stimulating
hormone (FSH) and
luteinizing hormone (LH).
Recent evidence suggests a direct inhibitory effect at gonadal sites
and a binding of
danazol to receptors of gonadal steroids at target organs. In
addition, danazol has been
shown to significantly decrease IgG, IgM and IgA levels, as well as
phospholipid and IgG
isotope autoantibodies in patients with endometriosis and associated
elevations of
autoantibodies, suggesting this could be another mechanism by which it
facilitates
regression of the disease.
In the treatment of endometriosis, danazol alters the normal and
ectopic endometrial
tissue so that it becomes
